i3c: mipi-i3c-hci: Add missing TID field to no-op command descriptor
commit ec3cfd835f7c4bbd23bc9ad909d2fdc772a578bb upstream.
The internal control command descriptor used for no-op commands includes a
Transaction ID (TID) field, but the no-op command constructed in
hci_dma_dequeue_xfer() omitted it. As a result, the hardware receives a
no-op descriptor without the expected TID.
This bug has gone unnoticed because the TID is currently not validated in
the no-op completion path, but the descriptor format requires it to be
present.
Add the missing TID field when generating a no-op descriptor so that its
layout matches the defined command structure.
